Check Digit Verification of cas no

The CAS Registry Mumber 4554-93-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,5,5 and 4 respectively; the second part has 2 digits, 9 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 4554-93:
(6*4)+(5*5)+(4*5)+(3*4)+(2*9)+(1*3)=102
102 % 10 = 2
So 4554-93-2 is a valid CAS Registry Number.

Novel triphenyltin substituted derivatives of heavier alkaline earth metals

Englich, Ulrich,Ruhlandt-Senge, Karin,Uhlig, Frank

, p. 139 - 147 (2000)

The synthesis and characterization of a family of novel alkaline earth metal stannides, in addition to tri- and pentastannanes are described. [Ba(18-crown-6)(HMPA)2][SnPh3]2 (4), [Ca(18-crown-6)(HMPA)2][Sn(SnPh3)3]2 (5), and [Sr(18-crown-6)(HMPA)2][Sn(SnPh3)3]2 (6) were synthesized by insertion of the corresponding alkaline earth metals into the tin-tin bond of hexaphenyldistannane. Ph3SnSnPh2SnPh3 (7), and Sn(SnPh3)4 (8) became available by treating 4 with diphenyldichlorostannane. All compounds were studied by NMR spectroscopy, and X-ray crystallography. The stannanes 7 and 8 were also characterized by elemental analysis.
